yesterday I was in Admin Painel of Magento, but today when I tried to access it again, it says “An error has happened during application run. See exception log for details.” I tried to setup:upgrade but I can’t run any command in the terminal it says: Class “Swissup CoreHelperComponent” not found#0 C:xampphtdocsmagento2vendormagentoframeworkObjectManagerFactoryCom

in the debug log says: main.CRITICAL: Error: Class “SwissupCoreObserverBackendFetchNotifications” not found in C:xampphtdocsmagento2vendormagentoframeworkObjectManagerFactoryAbstractFactory.php:121
This is what line 121 of AbstractFactory.php has: return new $type(…array_values($args));
Can someone please explain how to solve this error I need this solved for Thursday!
